tia_tia [17]

Answer:

See attachment

Step-by-step explanation:

We want to graph the line with slope

$m = \frac{2}{5}$

and y-intercept ,

$b = - 7$

The equation of this line is

$y = \frac{2}{5}x - 7$

Starting at -7 on the y-axis, we run 5 units and rise 2 units right.

Then draw a line through the y intercept and the new point

The graph is shown in the attachment.

Solve for x in the diagram.

Kazeer [188]

It is a right triangle so,

a² + b² = x²
9² + 12² = x²
225 = x²
√225 = x
15 = x

Hope this helps :)
